The gap has partially been filled in [1]}.
We found there that the charge
\({\cal C}\)  becomes in fact a very natural component of the
formalism.
Still, our
satisfaction remained limited because the operator-product
metric \(\Theta ={\cal PC}\)  did not seem to be
easily re-factorized
(i.e., in effect, interpreted) in terms of a
single Dyson map \(\Omega \) .
Also
the most common re-factorization
\(\Omega =\sqrt{\Theta }\)  of the metric (as recommended, e.g.,
in [2]}) may often prove too artificial.
